Hydrolysis of polysaccharides is a key step in biorefineries processes. In this study, an economic and green approach was developed to hydrolyze soluble polysaccharides (starch, inulin, etc.) into monosaccharides by a natural clay of attapulgite (ATP) modified with H₂SO₄(ATPS), and the catalysts were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), Pyridine FTIR Spectroscopy (pyridine-FTIR), Temperature Programmed Desorption of Ammonia (NH₃-TPD), Thermo-Gravimetric/Differential Thermal Analyze (TG-DTA). The hydrolysis of different substrate over ATP-S was evaluated.

活性凹凸棒石对多糖的有效水解

多糖的水解是生物精炼过程中的关键步骤。_{本研究采用H 2} SO ₄ (ATP  S)修饰的凹凸棒土(ATP)天然粘土将可溶性多糖(淀粉、菊粉等)水解成单糖的经济绿色方法，催化剂为通过傅里叶变换红外光谱 (FT-IR)、吡啶 FTIR 光谱 (吡啶-FTIR)、程序升温解吸氨 (NH ₃ -TPD)、热重/差热分析 (TG-DTA) 表征。评估了不同底物在 ATP-S 上的水解。
